No there is no way to simply feel around for a baby, at least not early in the pregnancy. You can get a test from a drug store that are reasonably accurate. Or you could visit your doctor. There are also many reasons for missing your period, or having it come late. If you've recently started or stopped taking birth control pills, or other hormonal drugs your system could miss a period, or be late while it adjusts.
Sometimes even things like stress can cause changes to your monthly cycle. Worrying that you're pregnant can add to this stress putting more stress on your body. The best thing you can do is get a real test done to know what you're facing. My grandma says she could tell if someone is pregnant just by looking at them but I don't know if I would trust that either, get a home pregnancy test or see your doctor.
